Patent number: 9631514Abstract: An axial-flow turbine according to an embodiment includes a plurality of nozzle structures and a plurality of blade structures. At least one nozzle structure includes an outer ring diaphragm and an inner ring diaphragm. The outer ring diaphragm and the inner ring diaphragm form an annular opening portion which extends in a circumferential direction therebetween. A nozzle is provided in a portion of a region of the annular opening portion in the circumferential direction, and a closing part is provided in another portion of the region of the annular opening portion in the circumferential direction. The closing part closes this other portion of the region to prevent a working fluid from flowing into this other portion of the region. A closing part medium passage is provided in the closing part and is configured to flow a cooling medium which cools the closing part.Type: GrantFiled: February 19, 2014Date of Patent: April 25, 2017Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Akihiro Onoda, Yuki Mimura, Shoko Ito

Publication number: 20140304988Abstract: In a method for manufacturing a channel-type brush seal of an embodiment, a cored bar is made to abut on a bundle of thin wires and the bundle of thin wires is bent at a part at which the cored bar abuts on the bundle of thin wires. Here, the cored bar is made to abut on the bundle of thin wires so that an extending direction of the thin wires in the bundle of thin wires is inclined with respect to an extending direction of the cored bar, and then the bundle of thin wires is bent, to thereby make extending directions of the bent thin wires intersect. Next, the channel is bent so that the channel sandwiches and fastens the bundle of thin wires and the cored bar at a part at which the bundle of thin wires is bent.Type: ApplicationFiled: April 7, 2014Publication date: October 16, 2014Applicant: Kabushiki Kaisha ToshibaInventors: Tatsuo YAMASHITA, Yuki MIMURA, Yoshifumi IWASAKI
